days filter – docs and examples optimisations (#2972)

* Replacement icon stopwatch on

As discussed in issue #2690

* Replacement icon stopwatch off

As discussed in issue #2690

* Added missing tag "Resources" (Community Resource)

* Tried to make a sentence clearer

CamelCase words are NOT joined with hyphens (copy-paste error?). 
Copied "directly" from the line below to make the meaning even clearer.

* Does deleting make the conflict go?

* Recreate deleted file with updated text

* days filter example should show highlights

- show a highlight using a longer timespan (180 days)
- added a second highlight to demo timespan with start AND end in the past
- better readability

* days Operator explanation optimisations

- typo
- readability (explain { positive | negative } first; remove duplication)

* Remove additional blank line

* Remove whitespace after save button

When the save button was not the last edit button (tested by moving to another place via control panel > Appearance > Toolbars > Edit Toolbar by drag-and-drop) then we got additional spacing due to whitespace in the resulting HTML after the button. This is a fix for that, I discovered while developing additional edit buttons.
